dear shader gods, I have a problem I am unable to solve. maybe one of you has an idea if this is doable at all on gpu:
I have geo-localized data points. Data comes baked in 32bit channel RGBA. At each point, my shader draws geometry. I also want to visualize the value (attached to that point) in form of numbers - using a glyph shader like the beta dx9 Ascii effect. I got everything working so far, except:
I always display an integer or float using 5 glyphs. let’s say “32.2”.
my 5 glyph-domains should know to display “(empty)” “3” “2” “.” “2”
I thought, maybe something can be done on the byte of bit level to achieve this.
